Netsight issue with access to the devices

When I right-click a device in a device tree no context menu appears. I also get ERROR in a Current Link column whenever I try to poll interface summary flexview. In the inventory tab below there is a message saying that the user has no access to these devices, although SNMP contact is established to all of the devices. What could be the issue?

It sounds like this may be an SNMP configuration issue on the switch itself. Can you show the output of a "show config snmp" and check to see if the user has the correct MIB view set for the access role of the SNMP group?

First of all thank you for your reply. Below is the snmp config for the switches. As you can see the snmp access parameters are as in default snmp config. I had no problems managing these devices with this snmp config in Netsight before, but after a while I got the issue described above (None of the configurations were changed on both Netsight and switches). I even tried to connect the defaulted Enterasys switch to the network and access it via the default public access accounts and I still get that problem - the SNMP contact is established but I cannot poll any data, except device serial and system info. All strings in snmp access parameters match the viewname parameters. I tried to snmpwalk one of the switches from the Netsight server command line using the same snmp access credentials and I get the full MIB tree, so I believe that the access credentials are fine.

Well, as I mentioned before when I right-click the device no menu appears and I cannot poll any info from the device. However, whenever I try to build a topology map, everything works fine, and all of the overlays work fine too, which means it does get data like STP and VLAN info from the device to build those maps. Any ideas?

I've tried that already - it didn't help. As far as I remember I first noticed the problem when I loaded netsight through ubuntu via IcedTea Java Launcher, but I don't see how it could mess everything up. And thank you again for your efforts.

Would you be able to access console using a windows platform and the oracle Java platform? It should like there may be issues loading using the iced tea. Particularly because you can't right cick devices.

I could access the console from windows platform before I tried IcedTea Java (Ubuntu) and everything worked fine. When I accessed console via IcedTead Java for the first time I've encountered this issue. Then I switched back to the windows platform client but the problem remained. Answering to your question - I can access the Netsight from Windows, but I cannot poll the devices in any way, except when using topology manager. Topology Manager works fine.
